Description

Technical Field

[0001] This utility model relates to the field of optical glass processing technology, and in particular to a rotary positioning optical glass cutting platform frame. Background Technology

[0002] Optical glass has wide applications in modern optoelectronics, display panels, and precision instruments, and its cutting precision directly affects the quality of the final product. In traditional glass cutting processes, the cutting platform is mainly responsible for clamping and positioning the glass sheet. However, existing cutting platform frames have revealed significant shortcomings when dealing with materials like optical glass, which come in various sizes and require extremely high processing precision.

[0003] Currently used cutting platform frames often employ manual adjustment or simple mechanical limiting mechanisms for their clamping mechanisms. When switching between cutting different sizes of glass, operators must rely on experience to manually adjust the width and position of the clamping mechanism. This process is not only time-consuming and labor-intensive, significantly reducing production efficiency, but also, due to the intervention of human subjective factors, it is difficult to ensure the uniformity of clamping force on both sides and the precise synchronization of positions, easily leading to unstable clamping or improper clamping force, thus damaging the glass. Furthermore, for optical glass requiring multi-angle or circular cutting, its positioning rotation often relies on a manual indexing plate or a simple mechanical rotating mechanism. This manual operation has limited positioning accuracy and lacks an effective self-locking mechanism. During the cutting process, it is easily affected by vibration, causing angular deviations, ultimately resulting in excessive errors in the cut finished product, failing to meet the high-precision processing requirements of optical glass.

[0004] Therefore, this utility model proposes a rotary positioning optical glass cutting platform frame to solve the problems of low adjustment efficiency of the clamping mechanism, insufficient positioning accuracy, and inaccurate rotary positioning when cutting optical glass of different sizes in the prior art. Utility Model Content

[0005] In view of the problems of existing optical glass cutting platform frames, such as the need for manual adjustment of the clamping mechanism, low adjustment efficiency and insufficient positioning accuracy, and errors caused by manual rotation positioning, this utility model aims to provide a rotary positioning optical glass cutting platform frame with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a rotary positioning optical glass cutting platform frame, including: a cutting bed, a clamping mechanism, a rotating mechanism and a cutting machine, with a worktable provided on the top of the rotating mechanism.

[0007] The clamping mechanism includes a slide rail plate fixedly mounted on the top of the cutting bed, a power assembly, and two sets of clamping assemblies. The power assembly includes a first servo motor fixedly mounted inside the cutting bed, two bevel gears, two bevel gears, and two lead screws. The output shaft of the first servo motor is fixedly connected to the bevel gears. The two lead screws are rotatably connected inside the slide rail plate, and the threads of the two lead screws are in opposite directions. The inner side of the lead screws is fixedly connected to the bevel gears.

[0008] The second bevel gear meshes with the first bevel gear on the lead screw. The first servo motor drives the two lead screws to rotate synchronously and in the same direction through the bevel gear transmission mechanism. The two lead screws are connected to the elongated plate by threaded engagement. Multiple spring plates are fixedly connected to the inner side of the elongated plate. The elongated plate slides on the slide groove plate. This structure, through the precise drive of the motor and the engagement of the reverse threaded lead screw, enables the clamping components on both sides to achieve synchronous, high-precision adaptive contraction and expansion, thus achieving precise clamping of glass of different sizes.

[0009] The rotating mechanism includes a second servo motor, a worm gear, a worm wheel, and a rotating rod, all fixedly installed inside the cutting bed. The output end of the second servo motor is fixedly connected to the worm gear, which meshes with the worm wheel. The worm wheel is fixedly connected to the outside of the rotating rod, which is rotatably connected inside the cutting bed. The worktable is fixedly connected to the top of the rotating rod. Through the transmission of the second servo motor and the worm gear, the worktable achieves a high-precision, self-locking rotational positioning function.

[0010] Preferably, the worktable is positioned below the cutting machine, with the cutting blades of the cutting machine perpendicular to the cutting area of ​​the worktable. This arrangement ensures that the cutting operation is applied accurately to the glass on the worktable, guaranteeing the precision of the cut.

[0011] Preferably, the elongated plate is slidably fitted into the guide groove of the slide plate by a fixed post. The fixed post is fixedly connected to the bottom of the elongated plate by screws. The fixed post slides along the guide groove when the elongated plate moves, providing reliable guidance and support for the elongated plate and enhancing the stability and accuracy of the movement of the clamping assembly.

[0012] Preferably, the power assembly further includes a hollow long plate, and the two bevel gears are connected through the internal transmission of the hollow long plate. The hollow long plate is fixedly set on the cutting bed and surrounds the output shaft of the first servo motor and the outer periphery of the two bevel gears, serving as a protective cover to effectively prevent dust generated during glass cutting from entering the gear meshing area, thereby protecting the accuracy and service life of the transmission mechanism.

[0013] Preferably, the second servo motor is fixedly mounted on a support base inside the cutting bed, and the other end of the worm gear is also rotatably connected to the support base, providing stable support for both ends of the worm gear and ensuring the stability of the worm gear transmission.

[0014] Preferably, the rotating mechanism further includes a hollow short block, which is fixedly disposed inside the cutting bed and sleeved on the outside of the meshing area of ​​the worm and worm wheel, thus isolating and protecting the high-precision worm wheel meshing mechanism.

[0015] Preferably, the spring plate is a strip-shaped elastic metal sheet, and the elastic direction of the spring plate is perpendicular to the moving direction of the elongated plate. This elastic sheet setting can provide a gentle and uniform clamping force, effectively avoiding damage to the optical glass due to stress concentration during the clamping process.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting a reverse threaded lead screw transmission chain driven by a servo motor, realizes the synchronous opposite or opposite movement of the clamping plates on both sides. Combined with the flexible clamping of the spring plate, it solves the problems of manual adjustment and low clamping accuracy of the existing clamping mechanism. It achieves the technical effect of adaptively adjusting the clamping of optical glass of different sizes and ensuring stable clamping and avoiding damage.

[0017] 2. This utility model solves the problem of errors that easily occur in manual rotation positioning in the prior art by setting a worm gear transmission mechanism driven by a second servo motor to control the rotation of the worktable. It achieves the technical effect of enabling the worktable to realize high-precision and automated angle positioning, and utilizes the self-locking characteristics of the worm gear to ensure the stability after positioning.

[0018] 3. This utility model solves the problems of low automation, inaccurate positioning, and low efficiency of glass cutting platforms in the prior art by integrating an automated adaptive clamping mechanism and a precise rotary positioning mechanism on the platform frame, and achieves the technical effect of significantly improving the accuracy, stability and production efficiency of optical glass cutting.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figures 1 to 5 This utility model provides a rotary positioning optical glass cutting platform frame, which aims to solve the problems of the clamping mechanism 2 requiring manual adjustment and having low precision, as well as the errors caused by rotary positioning in the prior art.

[0024] like Figure 1 and Figure 2 As shown, a rotary positioning optical glass cutting platform frame includes a cutting bed 1, a clamping mechanism 2, a rotating mechanism 3 and a cutting machine 5 disposed on the cutting bed 1. The cutting bed 1 serves as the mounting base of the entire device, providing a stable support platform, while the cutting machine 5 is used to scratch marks on the glass surface.

[0025] The cutting bed 1 is internally equipped with a first servo motor 2041 and a second servo motor 301, wherein the first servo motor 2041 is used to drive the clamping mechanism 2 to move, and the second servo motor 301 is used to drive the rotating mechanism 3 to move.

[0026] The clamping mechanism 2 is one of the structures of this utility model, used for adaptive and precise clamping of optical glass of different sizes. The clamping mechanism 2 includes a sliding long plate 201 fixedly set on the top of the cutting bed 1 and two sets of symmetrical clamping components. The sliding long plate 201 is used to provide guidance and support for the movement of the clamping components. Two bevel gears 2044 are fixedly connected to the output shaft of the first servo motor 2041 in the power assembly 204. The two bevel gears 2044 are connected through the internal transmission of the hollow long plate 2042. The hollow long plate 2042 is fixedly set on the cutting bed 1 and surrounds the output shaft of the first servo motor 2041 and the outer periphery of the two bevel gears 2044, which plays a protective role.

[0027] Two sets of clamping components are slidably fitted on the slide rail long plate 201. Each set of clamping components includes a long plate 203 and multiple spring plates 202. The spring plate 202 is a strip-shaped elastic metal sheet, and the elastic direction of the spring plate 202 is perpendicular to the moving direction of the long plate 203. It is used to flexibly clamp the glass. Multiple spring plates 202 are fixedly connected to the inner side of the long plate 203.

[0028] The elongated plate 203 is connected to the lead screw 2045 in the power assembly 204 by a threaded engagement. The lead screw 2045 is rotatably connected inside the slide rail elongated plate 201, and the threads of the two lead screws 2045 are opposite in direction. A bevel gear 2043 is fixedly connected to the lead screw 2045, and a bevel gear 2044 meshes with the bevel gear 2043 on the lead screw 2045, thereby converting the rotational motion of the first servo motor 2041 into the synchronous reverse rotation of the lead screw 2045. This, in turn, drives the elongated plates 203 on both sides to move synchronously towards or away from each other through the reverse threads, realizing automatic adjustment of the clamping width. The elongated plate 203 is limited and slidably engaged in the guide groove of the slide rail elongated plate 201 by a fixed post 2046. The fixed post 2046 is fixedly connected to the bottom of the elongated plate 203 by screws, providing guidance and support when the elongated plate 203 moves.

[0029] The rotating mechanism 3 is key to achieving precise angle positioning. The second servo motor 301 in the rotating mechanism 3 is fixedly mounted on the support base inside the cutting bed 1. Its output end is fixedly connected to a worm gear 302, which meshes with a worm wheel 305. The worm wheel 305 is fixedly connected to the outside of a rotating rod 304, which is rotatably connected inside the cutting bed 1. The worktable 4 is fixedly connected to the top of the rotating rod 304 and is positioned below the cutting machine 5. The cutting blade of the cutting machine 5 is perpendicular to the cutting area of ​​the worktable 4. A hollow short block 303 is fixedly mounted inside the cutting bed 1 and is sleeved on the outside of the meshing area between the worm gear 302 and the worm wheel 305 to protect the meshing mechanism. The other end of the worm gear 302 is rotatably connected to the support base. The entire worm wheel 305 and worm gear 302 transmission chain can achieve high-precision automatic rotation positioning of the worktable 4.

[0030] Please refer to Figure 3 , Figure 4 and Figure 5 The clamping mechanism 2 is located in the power assembly 204, and the power assembly 204 forms a specific transmission connection with the aforementioned cutting bed 1 and the elongated plate 203 in the clamping mechanism 2.

[0031] The power assembly 204 includes a first servo motor 2041 fixedly installed inside the cutting bed 1, two bevel gears 2044, two bevel gears 2043, two lead screws 2045, and a hollow long plate 2042.

[0032] Two bevel gears 2044 are fixedly connected to the output shaft of the first servo motor 2041. A hollow long plate 2042 is fixedly mounted on the cutting bed 1 and surrounds the output shaft of the first servo motor 2041 and the outer periphery of the two bevel gears 2044, thus protecting the transmission components.

[0033] The function of the power assembly 204 is to provide a synchronous and opposite linear driving force to the elongated plate 203 of the clamping mechanism 2.

[0034] Meanwhile, the elongated plate 203 is slidably fitted onto the slide plate 201 fixedly mounted on the top of the cutting bed 1, and two lead screws 2045 are rotatably connected inside the slide plate 201 and have opposite threads.

[0035] In the assembled state, the second bevel gear 2044 of the power assembly 204 meshes with the first bevel gear 2043 on the lead screw 2045, and the lead screw 2045 is connected to the two elongated plates 203 by means of threaded engagement.

[0036] This servo motor-bevel gear-reverse lead screw 2045 transmission structure ensures that the two elongated plates 203 can achieve high-precision, synchronous, opposite or opposite movements under the drive of the first servo motor 2041, thereby achieving adaptive clamping of glass of different sizes.

[0037] The remaining structures of the clamping mechanism 2, such as the elongated plate 203 which is limited and slidably fitted within the slide groove elongated plate 201 by the fixed column 2046, and the spring plate 202 which is fixed to the inner side of the elongated plate 203, work together to achieve the final flexible clamping and stable movement.

[0038] In a preferred embodiment, to further define the precise position of the cutting operation, the worktable 4 is positioned below the cutting machine 5, and the cutting blade of the cutting machine 5 is vertically aligned with the cutting area of ​​the worktable 4. This vertically aligned arrangement ensures that the cutting action can be accurately applied to the predetermined position of the glass placed on the worktable 4.

[0039] In a preferred embodiment, to improve the stability and guiding accuracy of the elongated plate 203 during its movement, the elongated plate 203 is limited and slidably fitted within the guide groove of the slide plate 201 by a fixing post 2046. More specifically, the fixing post 2046 is fixedly connected to the bottom of the elongated plate 203 by screws. When the elongated plate 203 moves along the slide plate 201, the fixing post 2046 always slides within the guide groove, thereby providing stable guidance and support and preventing the elongated plate 203 from deflecting or shaking.

[0040] In a preferred embodiment, in order to protect the transmission components of the clamping mechanism 2, the power assembly 204 also includes a hollow long plate 2042. Two bevel gears 2044 are internally connected through the hollow long plate 2042. The hollow long plate 2042 is fixedly mounted on the cutting bed 1 and surrounds the output shaft of the first servo motor 2041 and the outer periphery of the two bevel gears 2044, effectively preventing external glass dust or debris from entering the gear meshing area.

[0041] In a preferred embodiment, in order to ensure the stability of the rotating mechanism 3 and the reliability of the transmission, the second servo motor 301 is specifically fixedly mounted on the support seat inside the cutting bed 1, and the other end of the worm gear 302 is also rotatably connected to the support seat, providing stable support for both ends of the worm gear 302.

[0042] In a preferred embodiment, in order to protect the meshing area of ​​the rotating mechanism 3, the rotating mechanism 3 also includes a hollow short block 303. The hollow short block 303 is fixedly disposed inside the cutting bed 1 and sleeved on the outside of the meshing area of ​​the worm 302 and the worm wheel 305, so as to play a role in isolation and protection.

[0043] In a preferred embodiment, in order to achieve flexible clamping of the optical glass and avoid damage, the spring plate 202 is specifically a strip-shaped elastic metal sheet, and the elastic direction of the spring plate 202 is perpendicular to the moving direction of the elongated plate 203. When the elongated plate 203 moves inward to clamp the glass, the elastic deformation generated by the spring plate 202 can provide a uniform and buffered clamping force.

[0044] Working principle: During the cutting process, the first servo motor 2041 in the power assembly 204 on the cutting bed 1 is started and drives the two bevel gears 2044 fixed at the output end to rotate. When the two bevel gears 2044 rotate, they will mesh with the bevel gear 2043 on the lead screw 2045 inside the slide long plate 201, so that the two lead screws 2045 rotate synchronously. Since the threads of the two lead screws 2045 are opposite, during the synchronous rotation, they will drive the long plate 203 in the outer clamping mechanism 2 and the multiple spring plates 202 on the adjacent side to retract and move away. The hollow long plate 2042 acts as a protective gear. During the retraction of the two long plates 203, the spring plates 202 on both sides contact and clamp the glass. Finally, the cutting machine 5 is started to drive the diamond cutting wheel to scratch the glass surface. Then, external force is applied to make the glass break along the scratch. The fixed column 2046 can ensure that the long plate 203 moves smoothly, thereby realizing the effect of adaptive adjustment of clamping and cutting according to the size of the glass being cut. When using the rotating mechanism 3, the second servo motor 301 is first started and drives the worm 302 at the output end to rotate. When the worm 302 rotates, it will mesh with the worm wheel 305 on the outside of the rotating rod 304, thereby causing the worktable 4 fixed on the rotating rod 304 and the top to rotate. The hollow short block 303 plays a role in the worm 302 and the worm wheel 305, thereby meeting different processing requirements, realizing automatic rotation adjustment and avoiding the problem of errors caused by manual adjustment.
